Flip Buildings

[Onidotmoe]

Some buildings aren't perfectly symmetrical, which would make it nice if you could flip a building before you placed it.
For instance the Craftsmerm House's door hole face Right-To-Left, in some situations it would look nicer when playing to have it be flipped to Left-To-Right, this would only affect the building's sprite and could be achieved by pressing a button before playing, would add a nice bit of variety to the already existing buildings.
